This morning I ohmed out tagged all eight injector pulse wires from the ECM connector, and routed them the way I want them to lay. I have to marry the 93 and 91 harnesses at this point. My engine injector harness is off of the 93 engine and is a bit different than the 91 ecm harness. You just need to know this part is not just plug and play, because the switch out of the two different years. I also ohmed out and tagged the 8 pulse wires off of the engine part of the harness. Do not rely on wire color alone. Some of these colors change when they get oil, heat, sunlight etc on them. I am going to retain the 93's wire layout across the engine. Tomorrow I will cut and solder the 16 wires and start on some of the sensors.
I have plugged all of the sensor connectors in along with the IAC. I have left about 24"s of wire on each connector. I also tagged all of the sensor wires on the ECM end before I cut them off for easy identification. I also untangeled all of the wires as best I could where they enter the ECM plugs. This cut down on half of the bulk of the birds nest there before I did it.
I have to work overnight tonight and Saterday night,will not get much done this weekend.

josef644,
Did you figure out how you will run the heater hose from the top of the V8 to the back of the engine?
And what have you done with the heater output of the V8 water pump?[This message has been edited by falcon_ca (edited 08-28-2009).]

I am gonna cap off the small inlet at the rear of the water pump inlet as the 88 has the return line merge back in near the rear of the coolant return pipe. The smaller outlet on the 4.9 thermostat housing will be my heater supply line. My coupe was a 4 cyl car so it has the water line at the rear side of the engine bay. I'll just rig me up an extension of some type and join them togeather. The same way Mickey_Moose did. (borrowed his picture):

Do yourself a favor and fill that fitting with JB Weld or epoxy before you put the rubber cap on. (I removed the inlet housing from the back of the water pump plate to do this.)
After a few years those rubber caps will deteriorate and split. Usually at a most inopportune time.
I never had it happen to me, but I was behind someone on a run through the mountains, who had it happen.
We all saw the huge cloud of steam and thought it was smoke. Hilarity ensued.  Not.

I had that happen on a 302 Ford once. I use a short piece of heater hose, and fit a metal plug in the end. Put a clamp on it, then just slide it on the nipple, and tighten a second clamp. On these 4.9 swaps it will never be seen anyway. Those rubber caps are worthless.

You can cut off the heater hose neck and turn it were you want to relocate the hose. In this case it is towards the tranny and away from the valve cover.

On your build how did you run your VSS sensor wire? Did you lay your wires along the intake, down the passenger side of the engine, then to the VSS plug, or distrubitor end underneath the exhaust manifold to the VSS plug. I don't want to fry these two wires.

If I sent you a fuel rail would you modify it like this for me? I really hate having the fuel lines running accross the rocker covers. I'll pay you well for you time.  [This message has been edited by Fieroseverywhere (edited 09-01-2009).]
